Was verursacht dieses Problem?

According to the SAP naming convention, the character '-' is not
allowed within an object name. Existing fields containing this
character are accepted nevertheless.
With the introduction of type definitions in the ABAP Dictionary, the
use of '-' in field names can be ambiguous. Example:
X and Y are structures:
X Fields Type Y Fields Type
B Y C DTEL3
B-C DTEL1 E DTEL4
D DTEL2
X-B-C is ambiguous. It can be the field B-C of structure X or component
C of structure B of X.
Structures with '-' in the field name can only be accessed in ABAP
programs with LIKE and not with TYPE. Structures in which fields
contain structures cannot be used only with TYPE.
In this structure, you therefore cannot use a new field with structured
type in which a component field contains the character '-'.

Wie behebe ich diesen Fehler?

Do not use field(s) with structured type or use only structured types
whose component fields do not contain '-'.
